This module can be used to provide GPIO accessability in a C/C++ program, including interrupt handler support. To overcome the issue of internal pin numbering that is different from header pin numbering (for example Raspberry Pi where pin 11 is internally called GPIO 17 etc), a look up table is defined in the header to allow for pin number translation from physical pins to internal representation.
For basic testing, three programs gpiotest.out, irqtest.out and waittest.out can be generated and run on a Raspberry Pi.
For Raspberry Pi systems, functionality has been added to configure pullup/pulldown on input pins.
There is extensive documentation available through doxygen.
